The screw hooks work well for me as they hold nice and tight when spinning and you don't need to touch the plug, which does away with the need for a scratch coat. I hang the belly hole on plastic straw covered nails after sealing to dry,then add the screws to hold before painting, clear coating and spinning.
The only thing is, there is an extra step of needing to apply some epoxy with a pipe cleaner to seal inside the 1/2 inch on both ends after you take the screws out before wiring.
